If you have a Self Directed Brokarage Account in your 401 k you can only transfer 50% of your money to SDBA and any contributions go to the managed side not the SBDA so unless you make bad choices and it dips below 50% you can not get any more into SDBA side, and you can not buy any stocks under $5,00 dollars. This is my money and I should be able to make my own choices. And these are not Goverment rules this is set by the teamsters.
